            Bug ID: 108039
           Summary: BASIC: Trying to create string too long segfaults
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: BASIC
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: mikekaganski at hotmail.com

Execute following macro:
Sub strOverflow
  Dim s As String, i As Integer
  s = "0"
  For i=1 To 31
  s = s & s
  Next i
End Sub

This segfaults both on 32- and 64-bit LibreOffice when memory allocation is
unsuccessful (maximum string size is 2147483638 = 2^31 - 10). LibreOffice
crashes.
